Diego Lainez is ready to play for Real Betis as early as this Thursday's Copa del Rey game against Real Sociedad, stated the 18-year-old Mexican forward in his presentation at the Spanish club on Tuesday.

Lainez arrived to Seville on Saturday, passed his medical examinations on Sunday, before training for the first time with his teammates on Monday. Now he is hoping to complete a momentous week with minutes against La Real in the round-of-16 cup clash.

Even with his extensive managerial resume, ESPN FC's Alejandro Moreno is unsure Tata Martino will be able to satisfy Mexico's high expectations.

In the media event ahead of the Liga MX final last month, 18-year-old Diego Lainez sat on a stool by the pitch inside Estadio Azteca and fielded questions for more than 30 minutes. The youngster, already a household name in Mexico, was one of the most sought-after players.

"How do you deal with all the speculation about European clubs being interested and the pressure of playing a final inside Estadio Azteca?" Lainez was asked.
